"Naked shorty" is just a stinky pink myth used to provide a scapegoat for front loaders, toxic lenders, the company itself selling stock. Here, from FINRA (aka - the regulator) is a description of what the market makers do and how short volume is completely meaningless:
Short interest is the only relevant measure of open measure of shares that would have to be covered, and even those aren't usually short positions being taken for stinky pinks. In order to do that short, $2.50 per share has to be maintained in a margin account, and that's a stupid thing to do for a maximum possible gain of a few pennies.
